Error: Failed to configure client: tls: failed to find any PEM data in certificate input

[vodelerk]

Hi, I'm following this tutorial: https://learn.hashicorp.com/tutorials/terraform/kubernetes-provider?in=terraform/kubernetes

working from windows 10 with kind, and after I try terraform apply

I'm getting this error: kubernetes_deployment.nginx: Creating... ╷ │ Error: Failed to configure client: tls: failed to find any PEM data in certificate input │ │ with kubernetes_deployment.nginx, │ on kubernetes.tf line 32, in resource "kubernetes_deployment" "nginx": │ 32: resource "kubernetes_deployment" "nginx" { │ ╵

I have already checked the box on Docker desktop to "Expose daemon on tcp://localhost:2375 without TLS"

any advice?

Thanks,

Hey @vodelerk, I think you incorrectly set your keys to authenticate your k8s provider. Can you revalidate?

[vodelerk]

according to the tutorial:

Define the variables in a terraform.tfvars file.

host corresponds with clusters.cluster.server. client_certificate corresponds with users.user.client-certificate. client_key corresponds with users.user.client-key. cluster_ca_certificate corresponds with clusters.cluster.certificate-authority-data.

this is the setup

maybe, I might be sleepy at this point, but I double-check, and looks like it's correct.

is there something I am not seeing?

[im2nguyen]

Oh, those values are base64 encoded. Can you try this? It should work and we'll update the guide soon. Thanks for reporting @vodelerk! :smile:

provider "kubernetes" {
  host = var.host

  client_certificate     = base64decode(var.client_certificate)
  client_key             = base64decode(var.client_key)
  cluster_ca_certificate = base64decode(var.cluster_ca_certificate)
}

[vodelerk]

now the terraform apply gets stuck waiting for the replicas to be ready,

if I check on the docker desktop logs for "terraform-learn-control-plane", I'm getting:

Welcome to Ubuntu 20.10!

I tried it with the tls client option checked and unchecked on docker desktop,

the error I got from terraform:

kubernetes_deployment.nginx: Still creating... [9m50s elapsed] ╷ │ Error: Waiting for rollout to finish: 2 replicas wanted; 0 replicas Ready │ │ with kubernetes_deployment.nginx, │ on kubernetes.tf line 32, in resource "kubernetes_deployment" "nginx": │ 32: resource "kubernetes_deployment" "nginx" { │ ╵

any advice?

[im2nguyen]

Hey @vodelerk, I tried on my Windows machine and wasn't able to reproduce this. Can you try reinstalling or upgrading your current version of Docker?

[vodelerk]

let me get that testing done in a new environment, and ill get back to you with the results!

[vodelerk]

I'm working from a clean environment, but I'm still getting the terraform error, this time I'm working with the debugging feature export TF_LOG=trace and I'm getting this:

any advice?

[im2nguyen]

Hey @vodelerk, I think this is an error with kind and Docker instead of Terraform.

Can you try running: kubectl get deployments? If it returns the deployments, we can isolate the issue

[vodelerk]

im getting this: $ kubectl get deployments NAME READY UP-TO-DATE AVAILABLE AGE scalable-nginx-example 0/2 2 0 8h

I installed kind from chocolatey,

should be 2/2 in ready according to the tutorial right?

[im2nguyen]

Yeah, this should be 2/2. I think there's something wrong with your kind and/or Docker instance

[vodelerk]

how did you get kind installed? what version of windows are you using? which updates are applied to your windows?
